-- List one pair only
-- State your reason why
As of now, I most regret selling my ESW9s. They were beautiful in both looks and sound, and they were portable to boot. I didn't have to wear IEMs all the time when I had those. I also liked the recable job I did to my pair.
Ahh, maybe I'll pick up another set sometime in the future.
Grado GS1000i. I couldn't afford keeping them after acquiring the PS1000. It was a trade where I let go another pair of headphones and added some cash. I liked the surrealistic and mind blowing soundstage of the GS1000i which appeared in top systems giving the feeling of floating in the air.
Why? I needed money to order the HM-602, but I couldn't sell my beloved RE-Zero. I miss the sound of a full sized headphone and I borrow my friend's HFI-580 regularly, but they simply don't have the sound I want. maybe I would be buying another pair in the near future.
AKG K501, without a doubt. I sold them when I sold all my other audio stuff. I thought I was slipping down the slope just a bit too quickly in the world of head fidelity, so I purged everything before I became monstrous. I ended up using the money for collegiate activities. . . .
Anyhow, I've had a hard time getting back to the point where I was. It's sad. Though, it's all really just one big work in progress . . . I guess.
It was my daily use/portable cans for almost a year and a half. Not only did they sound awesome, but they were very comfortable since they weigh almost nothing, but then I bought the MS-2's thinking they would be better, but I was very dissapointed. They really didn't sound that much better, and they were not near as comfortable. I had already sold my MS-1's by the point I realized it though. I just today bought another pair of MS-1's and I am never going to get rid of them again.
